Study of diurnal and seasonal variation of atmospheric trace gases is essential to understand our atmosphere. For this, daily zenith-sky scattered light observations have been made by UV-visible spectrometer during the period 200... see more

An extensive experiment (the Aspendale ISCCP Regional Experiment) to study the radiative and microphysical properties of mixed-phase clouds yielded aircraft profiles from 3 fully iced cirrus decks, 2 liquid water decks of stratocumulus and 2 mixed-pha... see more

This paper is aimed to improve the productivity of an existing conventional single slope solar still with modifications. In this study, the conventional solar still is modified by using reflectors, jute cloth and improved glass angle. The modified still p... see more

In this study, we focus on the polarization angle of light scattered by terrestrial atmosphere-surface systems. The polarization angle describes the orientation of the plane in which the linearly polarized portion of light propagates. We show for skylight... see more

A generally accepted value for the Radiation Amplification Factor (RAF), with respect to the erythemal action spectrum for sunburn of human skin, is -1.1, indicating that a 1.0% increase in stratospheric ozone leads to a 1.1% decrease in the biologically ... see more

This research aims to create a polycrystalline type solar panel design with a capacity of 100 Wp which is portable (foldable and easy to carry everywhere) and can rotate following the direction of the sun. Solar panels designed are made of Hollow Cm Iron,... see more

A pressurized system utilizing evacuated tube collectors with internal heat pipes was investigated for the production of hot service-water for domestic use during all seasons in Pretoria, South Africa. The investigation focused on the prediction of season... see more

The multi-angular reflectance information has been proposed for discrimination of classes of natural vegetation under different characterization approaches. Although apparently this method enables reliable definition of typical multi-angular spectral sign... see more

A general distribution function is suggested to predict both symmetrical and asymmetric diurnal global solar irradiance q (t) W/m2 received on a horizontal surface, where “t” is the local day time "h" .The distribution is given in terms of well-establishe... see more
